6 Steps of the
Scientific Method 1)Form a question 2)Develop a Hypothesis 3)Plan an Experiment 4)Experiment 5)Draw Conclusions 6)Apply the Results How many M&M's are in a regular sized bag? Think about something you have observed or have a question about. Possible questions: Why is the sky blue? Why can't I open my locker? Pick one of your questions that you can design an experiment about. Does a Brawny or Bounty paper towel absorb more water? How many M&M's are in a regular sized bag?
Can an experiment be designed for this question?
YES!! A hypothesis is a possible solution to your question. It is an educated guess that can be tested. If your results do not answer your question, make another hypothesis and begin again! If your results do not seem REASONABLE and accurate, go back to your hypothesis and do the experiment again. Remember that Thomas Edison did not invent light bulb on the first try! Success takes time and work! Thomas Edison said, "Opportunity is often missed by people because it is dressed in overalls and looks like work." Do not be afraid of hard work and do not be discouraged when an experiment does not go as expected! A hypothesis is NOT just a guess! It is based on your previous experiences and observations. From past experiences and observations, you know there are six colors of M&M's and there are several M&M's of each color in a bag. RED BROWN BLUE GREEN YELLOW ORANGE From past observations, you think there about ______ M&M's in a regular sized bag.
Can we test this hypothesis?
YES! If your results are reasonable and accurate, then apply your results. List materials needed and steps you will take. Materials:
~ 6 small bags of M&m's (The more bags you use, the more accurate the results will be!) Steps:
1)Open a bag of M&M's and count the number of M&M's.
2)Repeat with the remaining bags of M&M's.
3)Find the average number of M&M's per bag by adding the number of M&M's in each bag and dividing by six. Conduct your experiment. Rememer to always follow the safety rules! Count the M&M's! Make sure ALL the bags are the same size! Analyze your data. CAREFULLY look over your results and find the answer to your question! The average number of M&M's in a bag is ... Apply the results. Take your results and make a connection to the real world. Anytime you purchase a bag of regular M&M's, you will expect there will be around ______ M&M's in the bag. Make sure to share your results. If you keep new discoveries or even mistakes to yourself, no one else can benefit from your work! Could you imagine if Alexander Fleming kept his discovery to himself??? Bonus points to anyone who finds what Alexander Fleming discovered! :)
